Touch

E Ink based displays currently support a variety of solutions for touch. These solutions include inductive touch sensors, resistive sensor, capacitive sensors, or infrared sensors. Resistive pressure touch can be implemented using patterned electrodes on the display. For inductive touch, implemented with a stylus, a patterned electrode array behind display interacts with dedicated stylus. Finally, for capacitive displays, contact creates an increase in capacitance, & is sensed by controller IC. Infrared touch, a relatively new method, looks for a stylus or finder to break the light pattern over the display and respond accordingly.

Controllers

Found in most major electronic reader devices, EPD controllers and E Ink's EPD low-power consumption screen technology have been key factors in the rapid growth of the eReader market and the expanding range of mobile applications, such as eBooks, eNewspapers, tablet PCs, laptop secondary displays, eNotebooks, and eDictionaries. The controllers are either available as integrated products used in System on a Chip (SOC) designs for monochrome products, or as discrete controllers for both monochrome and color displays.

Power Management

E Ink has partnered with major Semiconductor firms to build integrated power management ICs (PMIC) that are compliant with E Ink voltage requirements for E Ink based displays. By using a PMIC, customers can greatly simplify the design, footprint, cost and implementation of an EPD display.
